Description
Technical Field
The invention belongs to the technical field of server system heat dissipation control, and particularly relates to a reliable heat dissipation control method and device for a server.
Background
In server hardware, detection of each temperature point often faces some unstable factors, and especially, the temperature value is not refreshed due to some abnormalities, and no warning information exists, so that the condition of untimely speed regulation is caused. For example, the CPU temperature of the X86 server is generally that a temperature sensor inside the CPU is read by the intel management engine ME and then transmitted to the BMC, so that the BMC calculates the corresponding fan speed according to the CPU temperature, and when some special operations are performed on the CPU, such as testing or debugging, the CPU may be executed with a hash instruction operation or other abnormal operations, so that normal services cannot be executed, and meanwhile, the temperature of the CPU cannot be transmitted to the intel management engine ME, and the CPU temperature obtained by the BMC cannot be refreshed at this time, and the fan speed cannot be normally adjusted.
The temperature of the memory is also obtained by the intel management engine ME from the memory through the I2C link and then transmitted to the BMC, when the temperature sensor of the memory cannot be accessed due to the abnormal link of the memory I2C, the strategy executed by the intel management engine ME also keeps the temperature value unchanged without refreshing, and the BMC can normally access the temperature value of the ME but always obtains the value before the abnormal link; in addition, although other temperature points on the mainboard are directly obtained by the BMC through the I2C, the abnormal condition of the link can be sensed, but if the sensor damages the internal temperature value and the internal temperature value is not refreshed, the abnormal temperature value obtaining can be caused.
The CPU executes the hash instruction or the memory I2C link is abnormal, so that the temperature value of the intel management engine ME is not refreshed, the temperature value is not refreshed due to the fault of the sensor, the temperature value taken by the BMC from the intel management engine ME or the sensor is a value which is not refreshed all the time, the heat dissipation regulation and control risk is caused, and the fault is diffused.
Therefore, it is very necessary to provide a method and an apparatus for controlling reliable heat dissipation of a server to overcome the above-mentioned drawbacks in the prior art.
